WeChat Pay product coupon integration solution covering coupon type selection and the full lifecycle of issuance, redemption, lookup, refund, and callbacks. Provides five capabilities: selection guidance, sample code, business quick reference, quality assessment, and troubleshooting. Use when the user mentions “product coupon,” “issue coupon,” “redeem,” “create product coupon,” “product coupon code,” “product coupon callback,” “refund product coupon,” or asks to “integrate product coupons,” “generate coupon issuance code,” or “troubleshoot product coupon issues.”
Validate that analytics and marketing tracking fire CORRECTLY: GA4/GTM dataLayer events, Meta/TikTok/LinkedIn pixels, and ad-tech tags. Covers building a tracking plan as the contract, intercepting collect-endpoint beacons and dataLayer.push in Playwright, asserting event name + params + values + timing + de-duplication, Consent Mode v2 gating, CI regression gating, and news-media events (article-view, scroll-depth, paywall). Use when: "test analytics tracking," "GA4 event test," "verify the pixel fires," "dataLayer test," "tracking plan," "Meta Pixel dedup," "scroll-depth tracking test," "gate tracking in CI." Not for: whether tracking is ALLOWED to fire under consent law (GDPR/CMP) — that is compliance-testing; this skill checks the data is CORRECT. SEO meta tags / structured data — out of scope. Related: compliance-testing, playwright-automation, api-testing, qa-project-context.
Guides the agent through creating and maintaining Capacitor plugins from scratch. Covers scaffolding a new plugin project, designing the TypeScript API, implementing native iOS (Swift) and Android (Java/Kotlin) bridges, implementing the web layer, defining TypeScript type definitions, plugin configuration values, plugin hooks, development workflow with local testing, documentation generation, and publishing to npm. Do not use for installing existing plugins into an app, upgrading existing plugins to newer Capacitor versions, adding SPM support to plugins, or non-Capacitor plugin frameworks.
Creates reusable Convex components with defineComponent, a clean client wrapper, their own schema, and an npm publish setup. Use when extracting a feature into a package, building something for the Convex component directory, or when a component's functions are not showing up in the parent app.
Develop AI-powered applications using Genkit in Go. Use when the user asks to build AI features, agents, flows, or tools in Go using Genkit, or when working with Genkit Go code involving generation, prompts, streaming, tool calling, or model providers.
Work on one hard mathematics problem in this session yourself, with no sub-agents: reason in stages, record each settled step in a notes file so that nothing written is lost if a response is cut off, and end with a self-contained proof.md. Usage: /math-proof:solo <the problem, stated in full, or the path of a file holding it>
Use when implementing localization and translated copy in VTEX IO apps. Covers the `messages` builder, `/messages/*.json`, `context.json`, frontend message usage, and how VTEX apps integrate with `vtex.messages` for runtime translation. Use for storefront, admin, or backend flows that should use VTEX IO message infrastructure instead of hardcoded strings
When the user wants to implement IndexNow, notify search engines of new/updated URLs, or speed up Bing indexing. Also use when the user mentions “IndexNow,” “Bing indexing,” “URL notification,” “instant indexing,” “sitemap IndexNow sync,” “share URL list with sitemap,” or “IndexNow API.” For sitemap SSOT, use xml-sitemap.
When the user wants to reduce churn, improve customer retention, or plan lifecycle marketing. Also use when the user mentions "retention," "churn," "customer lifecycle," "churn prevention," "at-risk customers," or "loyalty program." For lifecycle, use growth-funnel.
When the user wants to improve crawlability, fix orphan pages, or optimize site structure for search engines. Also use when the user mentions "crawlability," "crawl budget," "orphan pages," "internal links," "site structure," "site crawlability," "infinite scroll," "pagination," "masonry SEO," "AI crawler optimization," "GPTBot crawlability," "ClaudeBot crawlability," or "content not indexed." For internal links, use internal-links.
Estimate how long a coding task will take using the user's own measured history instead of intuition. Use this skill whenever someone asks for an estimate, ETA, timeline, or deadline for a feature, bug, refactor, migration, script, or investigation—"how long will this take", "give me an estimate", "how many hours is this", "can this ship today", "is this a one-day job", "how many days for the whole epic", "what should I tell the client", "estimate this ticket", "size this"—and equally when the ask is skeptical ("is that realistic", "why did that take three days"). Also use it for the machinery behind the estimates—setting up or calibrating estimation, backfilling the task ledger from past Claude Code transcripts, recording a finished task's actuals ("record this task", "log this one", "add this to the ledger"), and rerunning calibration or checking whether past estimates were any good. Trigger it even when the word "estimate" never appears—a question about how much work something is, or how long something took, is this skill.
TikTok Creator Marketplace strategy and campaign management. Finding creators, negotiation tactics, campaign execution, performance tracking, and relationship building. Use when the user asks about TikTok Creator Marketplace, finding TikTok creators, creator partnerships, or influencer campaigns.
Brand monitoring tool for tracking mentions across social media platforms. Monitor Reddit, Google News, YouTube, and DuckDuckGo for brand mentions. Includes sentiment analysis, trend tracking, crisis detection, and competitor comparison. No API key required for basic monitoring.
Core Catalyst project setup — directory structure, environments, CLI commands, and all Catalyst IDs (Project ID, ZAID, Table ID, Segment ID, Org ID). Trigger on 'start a Catalyst project', 'what is .catalystrc', 'where do I find my Table ID', 'difference between Development and Production', or any Catalyst ID or CLI question.
Automated coordination, formatting, and learning from Claude Code operations using intelligent hooks with MCP integration. Includes pre$post task hooks, session management, Git integration, memory coordination, and neural pattern training for enhanced development workflows.
Ilya Sutskever’s thinking framework and communication style. Based on in-depth research into 12 first-hand conversations, 9 academic papers, 10 hours of sworn testimony, a list of 27 recommended readings, and 14 authoritative secondary sources, it distills 6 core mental models, 8 decision-making heuristics, and a complete communication DNA. Use as a thinking consultant to analyze AI technology directions, safety strategies, and research taste from Ilya’s perspective. Trigger when the user says “from Ilya’s perspective,” “what would Ilya think,” “Ilya mode,” “ilya perspective,” or “sutskever perspective.” Also trigger for requests like “help me think about this from Ilya’s angle,” “what would Ilya do,” or “switch to Ilya.”
Bulk-regenerate broken test selectors after a UI refactor or redesign. Detects drift between old and new DOM with an aria-snapshot diff, maps old locators to new equivalents using role-first + region scoping, validates against the new build, and produces a single PR with grouped per-file selector updates and per-change evidence. Assumes Playwright >= 1.50 (trace viewer DOM-snapshot panel, getByRole filtering, ariaSnapshot). Use when: "UI refactor broke tests," "redesign broke tests," "bulk update selectors," "regenerate selectors after refactor," "selector drift," "fix N broken tests after redesign." Not for: healing one flaky test at runtime — use test-reliability. Not for: writing a new test suite from scratch — use playwright-automation. Not for: re-recording tests after a framework switch (Selenium to Playwright) — use test-migration. Related: test-reliability, playwright-automation, test-migration, ci-cd-integration, visual-testing.
Sets up and debugs remote push in Capacitor apps with @capacitor/push-notifications (FCM on Android, APNs on iOS), or Capgo alternatives @capgo/capacitor-firebase-messaging and @capgo/capacitor-notifications. Covers APNs keys, Push Notifications capability, AppDelegate `didRegisterForRemoteNotificationsWithDeviceToken` forwarding (stays in AppDelegate under the Capacitor 8.5 UIScene lifecycle), Android 13+ POST_NOTIFICATIONS permission, notification channels and icons, `firebaseMessagingVersion`, foreground `presentationOptions` (Capacitor 9 removes iOS `alert`; use `banner`/`list`), and tap routing. Use when `registration` never fires, iOS returns an APNs token instead of an FCM token, errors like "no valid aps-environment entitlement string found" appear, or notifications do not show. Do not use for local-only notifications or deep link URL handling (capacitor-deep-linking), UIScene migration (capacitor-uiscene-migration), or log capture (ios-android-logs).
Use when scraping JavaScript-heavy pages or SPAs, crawling multiple URLs concurrently, extracting structured data with reusable CSS/JSON schemas, or building automated web data pipelines. Wraps the Crawl4AI library (`crwl` CLI and Python SDK) with schema-generation patterns for LLM-free extraction. Triggers on crawl4ai, crwl, scrape JS-heavy site, scrape SPA, headless browser scrape, schema-based extraction, batch crawl, sitemap crawl, web data pipeline. SKIP when a static HTML page can be read with `defuddle` / `fetch-web` — those are faster cold-start and don't need a browser.
Build and refine high-craft web interfaces: brand sites, product dashboards and workflows, AI workbenches, commerce, H5/mobile screens, and individual components. Route by purpose, preserve project identity, and audit visual quality, accessibility and motion. Supports Apple-inspired / 苹果风 design through editorial, app and spatial modes with runnable card studies. Use for landing pages, portfolios, dashboards, admin panels, settings, agent consoles, product pages, checkout, mobile app UI, design-system extraction, redesign, typography, color, layout, animation, drag/swipe/sheet interactions and anti-generic iteration. Includes targeted audit, bolder, quieter, soul, diverge, animate, depth, densify, init and document workflows. Excludes backend-only tasks
Guide for migrating Apache Airflow 2.x projects to Airflow 3.x. Use when the user mentions Airflow 3 migration, upgrade, compatibility issues, breaking changes, or wants to modernize their Airflow codebase. If you detect Airflow 2.x code that needs migration, prompt the user and ask if they want you to help upgrade. Always load this skill as the first step for any migration-related request.
Data engineering skill for building scalable data pipelines, ETL/ELT systems, and data infrastructure. Expertise in Python, SQL, Spark, Airflow, dbt, Kafka, and modern data stack. Includes data modeling, pipeline orchestration, data quality, and DataOps. Use when designing data architectures, building data pipelines, optimizing data workflows, implementing data governance, or troubleshooting data issues.
Work on one hard mathematics problem in rounds: each round a judge writes a few self-contained questions, independent workers answer them, and the judge keeps a ledger of what is proved, refuted and open, until the judge concludes or the rounds run out, and then a proof.md says plainly what is and is not proved. A run takes hours and dozens of worker runs. Usage: /math-proof:siege [NAME=value settings] <the problem, stated in full, or the path of a file holding it>
Use to reverse-engineer why a piece of content went viral (or overperformed) — yours or someone else's — and extract the repeatable mechanism to apply to your own content. Run when the user says "why did this go viral," "break down this viral post/video," "reverse engineer," "what made this work," or wants to learn from viral content. Sources the observable signal first (intake, transcript, screenshots, top comments, visible stats — an agent usually can't watch a video from a link) and never fabricates what it can't see. Reads brand-profile and audience first, deconstructs the piece layer by layer, isolates the real driver, runs a replicability check, extracts the transferable principle, and applies it to the user's niche via the content skills. Mechanism, never a copy; flags non-replicable virality; visible signals only (no WoopSocial analytics). Single-POST teardown only: for the account-level competitive landscape use competitor-analysis; for riding a live trend use trend-jacking.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
